We purchased 1' x 1' tiling sheets. The tiles are about 2" x 1". The tiling guys didn't use spacers everywhere. They taped the sheets and sometimes used spacers where the sheets met (and not everywhere they met).
Some of the tiles were also not flat with the plane of the other tiles.
Also, how come there is so much thinset(?) between the tiles right now? The grout hasn't even been applied.
How would all these issues be fixed? We are going to be using a dark contrasting grout so all of these mistakes will be magnified.
update 11/24
The contractor basically removed individual tiles and fixed 99% of the tiles.
We still haven't grouted yet. Going to carefully inspect.
